I should have added that when 'they' think a player is going to win a match, security move in to control autograph hunters. If you're the other player, you might notice it even though it's happening behind you. As you look at the screen for this court, they will move in on the bottom right hand side of the Melbourne sign. They moved in when they thought Verdasco was going to win, only to move away again when it went to a 5th set .
